Component w/Train of dynamic regions

I'm working on a web application (JDeveloper 11 g), where a page has a dynamic directian with associated task flow that defines the fragment of the view. Most of the fragments for this region, use a template page with a component of train. Navigation using the train for the most part works fine him fragment is replaced by a new snippet each time you click on a link of train.

However, a single fragment contained another dynamic region. "I tried to define the scope of the bean to manage this region to viewScope, but I get a message popup in the browser 'viewScope.myManagedClass.dynamicTaskFlowId' is invalid" when I click on the link to train for the fragment component. I get a similar error, if I updated the scope of bean to the session or pageFlow. Only when I set the scope to the backingBean or neither avoid the error message.

But then another problem occurs. One of the fragments in the stream for the inner region has a panelAccordion with several showDetailItems of selectManyCheckboxes. The panelAccordion does not list anything and crashes if I try to open or close any showDetailItem. This behavior is similar when the scope of the bean, flow management is not set to viewScope or higher.

By stepping through the code, I noticed that flow to the outer region code runs after the event code trigger the internal region that sets the taskFlowId of the inner region, but before the workflow of the inland region, parameter taskFlowId in the inner region code is therefore lost. I tried to start session context and recover, and which almost works. If I select in terms of the selectManyCheckboxes, they are lost once I move to a different fragment in the region.

Does anyone have ideas on how to get to this page in collaboration, alternatives to the approach I take, I need to check the settings or any reference material, I could consult?

Thanks in advance!

Hello

However, a single fragment contained another dynamic region. "I tried to define the scope of the bean to manage this region to viewScope, but I get a message popup in the browser 'viewScope.myManagedClass.dynamicTaskFlowId' is invalid" when I click on the link to train for the fragment component.

The managed bean is defined in the metadata definition of the taskflow bounded that you load? Please note the stubborn workflow to initialize only their controlled beans when they are loaded. If you set the bean managed in the defined parent of the workflow then the viewScope is also the parent flow. Appears as if it is the problem you describe

Train does not not as expected with dynamic regions

JDeveloper version - 11.1.1.7.0
I created an application with 2 workflow with 3 defined fragments like a train. These workflows is deleted a page like dynamic regions. On the page running, in the first region the train works fine. But access to the second region, when I click on the 2nd train stop, the train navigates to the first fragment of the first step.
Note: I also created a test application, it was the replication.

I looked at your code and found the problem. The bean that you can switch regions is defined in the scope of evil. The TrainDynamicBean must be set in viewScope at least. If you set it in a scope less (backingBean or application) the bean is generated for each request. If you go to region 2 the bean is created again for the next request, and the taskflowid points again to flow available1. This is the reason why you see the view4 when you switch to flow2 but view5 clicking on flow available1.

It is a problem.when known and documented, working with dynamic regions. JDev creates the bean in the wrong scope, and you have to take it at least viewScope.

Problem with the identification of the Train in a dynamic region
Hello

I have a two task flows (firstflow, secondflow) and they both have their own individual trains and they are all fragments of the page. Then I have my main page, where I have created a dynamic region based on secondflow. Then, on the same page, I have links dynamic region for firstflow and secondflow. When I run the application I consult first the second rate and his train. Now, when I click on the link firstflow. the page is displayed, then when I click on the train, it then goes to the secondflow and his train, I can't navigte in the firstflow and his train. Please let me know any solution to this. Thank you.
Hi Baro,

Can you please try again, after you set the scope property of the managed bean that stores region Dynamics-flow-id of the task to the 'session' instead of 'query' in the adfc-config file. XML?

Kind regards

How to assign components page parent of a page fragment in a dynamic region

Hi, I am using JDeveloper 12.1.3. I have a single page request that contains a sidebar (with separator) on the left and a dynamic region on the right. One of the fragments of the page that appears in this dynamic region has a task flow that calls another fragment of page. What I do when this event occurs, it is to dynamically hide (or at least close) the left side panel. I created a bean of support that includes a method to do so. This method works very well when I call it from a test button on the parent page. But I can't understand how effectively call it a method in my stubborn workflow (page fragment). I created the method and incorporated it in the workflow. I refer to the method in the bean support. No errors are generated when I perform the navigation. I have debugging instructions that indicate support bean method is called. But the screen will not reflect the changes on the side panel. I tried to use a parent action in my stubborn workflow (and tried to have this action relative to call the method), but that did not help. I thank you very much for any assistance, you can provide.

The problem is that you can reach the panelSplitter of off the page on which it is located. If you use a methodcall activity that you call with a parent action you get a new instance of the separator, but not then, you try to change.

What you can try to bind the separator to a property of bean a bean view extended who resides in the workflow of the parent page. Then you pass this bean as a parameter to the flow of the task of the fragment and call the method within the bean. It of called bean reference and is listed in this article by Frank Oracle ADF May / June 2013. Make sure that you use a component for the bean property reference. On second thought, you might not even to bind the separator to the bean as you can look it up in the page directly using findComponent().

[ADF, JDev12.1.3] Why dynamic region is not spend if I re - call the currently displayed workflow?

Hallo,

I have a page with a dynamic region that is managed by a range backingBean bean.

Functions "startBtf...". "are called when a menu item is clicked.

The workflow as BTF3 is called by two different functions and each function passes a different value (used by a component of router) to the workflow through the hash table.

The problem is that startBtf3_Search is called after the startBtf3_Create (and vice versa) the dynamic region is not updated.

How can I solve this problem?

Thank you

Federico

The problem is that startBtf3_Search is called after the startBtf3_Create (and vice versa) the dynamic region is not updated.

How can I solve this problem?

You call the taskflow even without leaving the previous.

To update the workflow, you have several options:

-Give taskflow refresh 'ifNeeded' parameter and change the value of the input parameter (unfortunately, it is not applicable to your usecase because you use the parameter mapping and not point settings so setting change cannot be detected)

-use the property RefreshCondition

For more details, see: 23 by using task flows in regions (12 c (12.1.3))

BTW,

currentTaskflowId = "/WEB-INF/empty-btf.xml#empty-btf";

Instead, you can change the return type for getDynamicTaskFlowId() to a string and use an empty string ("" ") instead of emptying the BTF (and in this case you don't need even of TaskFlowId.parse (part)).

Refreshing dynamic region problem

Hello
I am facing problems refreshing the dynamic region. Here's the usecase:
JSPX page: TestDynamicTaskflow.jspx
First Taskflow: LinksTF--> has a page with 3 buttons control and a dynamic region.
Then click on the 1st and second command button link tf-1 must be displayed and for the third command button tf2.
Second Taskflow: tf - 1-> Taskflow has a page with an inputText field jsff (required = true)
Third taskflow: tf - 2-> Taskflow has a page with an inputText field jsff (required = true)
Problem: Click on the 1 button and tf1 is responsible. Now, enter a value for the inputText and click commandButton2... tf-1 is loaded but inputText retains the entered value... What is question.

Hello

the workflow is reloaded you should be able to tell when a print message set must be called in the initializer of workflow. I guess the problem is with the text component not reset its value. So it's a problem of lifecycle JSF, not a matter of the region. The command link pass the workflow, licensing

oracle.adf.view.rich.util.ResetUtils.reset (regionId_in_here);

Data for the problem of dynamic regions was interrupted
Hello. I use JDev 11.2.2 and stack complete ADF.

This is when I try to load a new stream of work of a dynamic region. Let me give a step by step test case:

1 - using HR, model of generation: create objects (entities, objects View) for the employees and departments tables and an Application Module.

2. - in VC, add a page facelets with layout of two columns, first for a tree for the switching of regions and a dynamic region in the second column.

3 - create a page fragment that includes a generated table view in data controls and another fragment of page view of departments.

4 - create two workflow bounded, for fragment employees and another for the fragment of departments.

5 - drag and drop workflow bounded to create a dynamic region in the second column of the home page. Of course by selecting backingBean for new bean (default value is increased demand).

6 - in the model, create a static filled List View object with two attributes: a workflow id and a description

7 - in VC, generate a tree in the first column of the home page

8. - write a component of the tree selection listener to read the id of the current workflow and set this ID value of workflow dynamic region at the appropriate bean.

9 - set triggers of partials in a dynamic region in the homepage to listen for events from the tree.

10 - run and try to load a new workflow clicking in the tree. An alert is triggered with this message:

* "The content of this page could not load as expected because data transmission has been interrupted. Please try again or contact your system administrator. » *

And the newspaper is displayed as a result of lines:

* < FaceletViewHandlingStrategy > < handleRenderException > error rendered View [index.jsf] *.

Problems updating of an image in a dynamic region
JDev 11.1.1.5 window 7 x 64 JDK 1.6_31

I have a (capchta) image in a dynamic region with a data form and the fields.
I use the SimpleCaptcha library (servlet) as any other image, she calls the servlet.
The image loads and works very well as well as the audit.

I wanted to put a button on the screen to refresh the image (get a new image essentially). (I have the sample application that does this as well).

Problem is that I can't seem to update (AJAX) without refreshing the entire page (manually).

I tried partial triggers (PPR) and just, they don't do anything.
I tried using a command button and adding a refresh stripped - still nothing.
Put it in a subform - no change.

All items from google are updates of the region to another - not not refreshing points the same region - is there a problem with that?
I use PPR a bit in other areas, but also stripped updates (these are all the buttons and text fields) - so I know PPR works within a region - same dynamics.
This seems to be related to the fact that it is a picture of servlet.

Someone there done this and can share the answer?
How do you refresh the image... did you provide the image element to cool... its best to refresh the image Refresh parent component using addPartialTarget...
surround the image with panelgrouplayout and refresh the component panelgrouplayout programmatically

I use a dynamic region in my web project. I use JDev 11.1.1.3 and use the built in weblogic server.

But there is no ADF faces DURATION 11.1.1.3 installed on its box.

Dynamic region in the Popup - clientListener problem?
Hello

I work in Jdeveloper 11.1.1.2, following the model of popup/region found at: http://www.oracle.com/technology/products/adf/patterns/11/popupregionpattern.pdf to have a dynamic region in a popup. I already have an active implementation on one of my pages, but the same exact implementation on another page gives me questions. Whenever I have add a component of af: clientListener to my popup, the table in the same panelCollection stops its rows of rendering. Display the column headings, but there is no text of any kind in the lines. If I delete the af: clientListener, my page works perfectly.

Here's my code for popup so far:
< af:popup id = "awdPU" contentDelivery = "lazyUncached".
launcherVar = 'source' eventContext "Launcher" = >
< af:setPropertyListener from = "#{source.attributes.saId} '"
to = "#{pageFlowScope.currentSaId} '"
Type = "popupFetch" / >
< af:setPropertyListener from = "#{source.attributes.saId} '"

Anyone know of any reason that a client listener would have this kind of impact on my page? I tried other types or methods, and it just seems as if an af:clientListener is there, it won't work.
Thank you!
Hello

I came across this type of problem. What do you call the javascript method it may contain errors or if the clientListner not able to find the method that you call in the jspx drop that behave like this only.
keep an alert beginning of the script (popupClosedListener) method and check if it is the call or not. Better related serverListner should be after the ClientListner.

Dynamic region on the change from the drop-down list of values

Hi Experts,
Using the concept of dynamic region, I tried to use buttons as I have 4 buttons and clicking on each button, I am loading the particular taskflow. I used setPropertyListener and type = action to achieve this.
I have a similar requirement, but I need to use the drop down list here...
< af:selectOneChoice value = "#{mybean.value}" >
< f: selectItem itemLabel = "First" Valeurelement = "FirstValue" / > "
< f: selectItem itemLabel = "Second" Valeurelement = "SecondValue" / > "
< f: selectItem itemLabel = "Third" Valeurelement = "ThirdValue" / > "
< f: selectItem itemLabel = "fourth" Valeurelement = "FourthValue" / > "
< / af:selectOneChoice >
How can I dynamically load a region on the value selected by the user on top of the data. On the change of the value in the drop-down list, I need to load this particular dynamic region
JDeveloper version 12.1.3
Thanks in advance.

You use a listener to change value of the duo down and detect the region according to the new value of the duo down.

Changes in validation ADF dynamic region on swap of the region

Hello
I use JDeveloper 12.1.3
In my application, we have a single page with a dynamic region. By clicking on the buttons of the region cools in a new page (a typical behavior of the dynamic region).
However, I have a question asking the user to commit changes in a page before moving out of the region. Is there a standard way to solve this problem?
To add to the question, if there are 5 (for example) regions with 5 buttons, each in the region is filled with a shared library.
Help, please.
Thank you
Kamal

How to access page aplication module of dynamic region?

Hello
I have a main app with the shared library. Page.JSFF (from the main application) contains dynamicRegion. Task flow for this dynamicRegion I defined in library shared sessionBean. I need call commit action in the main application for the data in a dynamic region.
How to access the application module or binding operation for page of workflow dynamic region?
I try to do this:
BindingContainer bc is BindingContext.getCurrent () .getCurrentBindingsEntry ();.
DCTaskFlowBinding dtb = (DCTaskFlowBinding) (bc) .findExecutableBinding ("dynamicRegion1") (DCBindingContainer);
System.out.Print ("" + dtb.getViewPort().getViewId()+"\n"); -return id correct view
Form JUFormBinding = dtb.findExecutableBinding ("test5PageDef") (JUFormBinding);
DCBindingContainer dcRegion = form;
OperationBinding o = dcRegion.getOperationBinding ("Commit");
o.Execute ();
but the result is NullPointerException
Jdev 11.1.2.4
Thank you

Hello

Try this:

BindingContext bindingContext = BindingContext.getCurrent ();

DCBindingContainer dcBindingContainer = bindingContext.findBindingContainer("myPageDef");

OperationBinding operationBinding = dcBindingContainer.getOperationBinding ("Commit");

operationBinding.execute ();

Kind regards

Dynamic region with several task page fragment flow isn't refreshing VO

JDeveloper version is 12.1.3 and Weblogic Server is 12.1.3.
We have a dynamic region with several task page fragment flow. We have created a menu that will open on the workflow task in the dynamic region. Before defining the workflow id in the bean, we execute query on the original Version after setting the bind variable. When we click on the menu is open the flow of relevant tasks in the region and showing the Original data table.
But when we open the same request again to a different browser session, it shows all the data in the original Version when the user clicks on the relevant menu item...
I have attached the code used to navigate to the different workflow tasks written in the bean from the back of the home page.
We have no idea why anyone what happens, if it's a server problem or a code issue. Because unless and until we open the target application in a new browser it works fine.
We tried and deployed on a remote server as well, but it gives the same question...
Would be really grateful for the help...

The user, the code you posted has some serious problems. Never, I repeat never store a reference to an application module in a static variable in a bean. That is why you see only data once. After that, the second session reuses the application module from the first to the configuration data, but to display data it uses a module different application.

The way you try to configuration data is too bad. You must pass the parameters to the workflow and init data in the default action of the workflow instead of doing before installing the new workflow id. A workflow is a unit of work that is kind of a black box. You may not assume that the stuff you do outside of this black box can be seen inside the box. This is only true if the workflow share the same control of data as it's parent (share of data control).

I suggest you read some documents on the workflow and how they work. A good start is to look at this video https://www.youtube.com/watch?v=A3CmDhWHaG0

ADF 11.1.1.7: Control a dynamic region of JSP with a SelectOneChoice

Hello user community:
I have a need to understand How to control content within a dynamic on a JSP page region. In the JSP page content within the dynamic region is determined by a selectOneChoice drop-down list presented to users... I have spent hours of research and cannot identify the exact procedure for this process. Please point me in the right direction. I look forward to any input provided.
Here is my scenario:
1. users will select a TransactionType in a drop-down list.
2. According to the selection selectOneChoice the loading of a page of .jsff within the dynamic region.
Details of the background:
- I have a dashboard for the details of the Transaction. This is the JSP page.
- I have 18 Transaction_Detail fragments of page based on your that take advantage of bind variables & discovers the criteria. Here are the pages JSFF '.
I want the JSP page to control what JSFF page is loaded in the menu-driven selection of users drop-down. I found a simplistic example of this ability in blog of Zeeshan Baig. However, the logic command what JSFF page is loaded if... otherwise based, and using a workflow IDs. I can use the flow ID of the task, but I only need 1 page JSFF responsible.

Thank you very much!

What you describe is a simple switch of dynamic regions. Watch the video of Shay https://www.youtube.com/watch?v=gNipIBn5Zv0

Instead use the links to the selected region, you put the id of the workflow in a list that you put on a LOV. When you select a new value LOV the region moves.
